STEVAL-IHM029V1:
2000 W universal motor control based on the STM8S103F2
Introduction
The STEVAL-IHM029V1 is a low-cost universal motor control demonstration board
designed for the home appliance market, with particular focus on vacuum cleaners, food
processors and power tools.
This system features the 20-pin, 8-bit STM8S103F2 microcontroller running at 16 MHz (RC
user-trimmable internal RC clock), featuring 4 KB of Flash memory, a 10-bit A/D converter,
2
8/16 bit timers, communication interfaces and 640 bytes E
PROM.
The power supply circuitry is based on the VIPer16LN, an off-line converter with an 800 V
avalanche-rugged power section, operating at 60 kHz.
The STEVAL-IHM029V1 can control any universal motor up to 2000 W, thanks to the
T1235H, a 12 A 600 V high temperature Triac. The motor control is based on phase-angle.
In order to limit the in-rush current and possible current peaks, the demonstration board
features a soft-start routine and a smooth power change function.
The board has passed the pre-compliance tests for EMC directives IEC 61000-4-4 (burst up
to 8 kV) and IEC 61000-4-5 (surge up to 2 kV).
In standby mode, the STEVAL-IHM029V1 has an overall standby power consumption below
300 mW.

Page 10: Functional Description
Functional description UM0922 Functional description The driving of the motor is based on phase-angle control. Figure 4. Phase-angle control The MCU operation is synchronized with the voltage mains thanks to the zero-voltage switching (ZVS) signal. This signal is sent directly to an MCU input pin, which is set as external interrupt. -
Page 11: Oscilloscope Waveforms
UM0922 Oscilloscope waveforms Oscilloscope waveforms The following waveforms were taken while testing the demonstration board with a 300 W universal motor and no load applied. The purpose of these waveforms is to show how MCU signals are managed and synchronized to the voltage mains. These signals are valid and remain unchanged for any universal motor connected to the demonstration board. -
Page 12: Figure 6. Motor Working At The Highest Power Level
Oscilloscope waveforms UM0922 Figure 6. Motor working at the highest power level The gate pulse (blue) is now applied to the Triac with a firing angle of 2.5 ms with respect to the voltage mains (brown). Once the pulse is applied, the Triac turns on and begins delivering power to the motor. -
Page 13: Figure 8. Soft-Start
UM0922 Oscilloscope waveforms The ZVS signal is used by the MCU as a reference to calculate the firing angle and to synchronize the Triac gate signal with the voltage mains. The ZVS signal ranges from 0.6 V and 5.6 V. This is due to the cutting diodes inside the MCU I/O port. -
